Human behavioural adaptation to delayed visual-motor feedback has been investigated by Miall and Jackson (2006: Exp Brain Res) in a closed-loop manual tracking task with a semi-predictably moving visual target. In intersensory, open-loop and predictable sensory-motor tasks, perceptual adaptation of the involved modalities has been demonstrated on several occasions in recent years, using temporal order judgments and perceptual illusions (e.g. Stetson, Cui, Montague, & Eagleman, 2006: Neuron; Fujisaki, Shimojo, Kashino, & Nishida, 2004: Nature Neuroscience).
Here we present results from two series of experiments: the first investigating perceptual adaptation in Miall and Jackson's tracking task, by adding visual-motor temporal order judgments; and the second investigating the localization of perceptual adaptation across the involved modalities.
We will discuss these results in the light of recent developments in modeling adaptation to misalignment in spatial (Witten, Knudsen, & Sompolinsky, 2008: J Neurophysiol) and temporal (Stetson et al, 2006) domains, and consider their implications for what, if any, common mechanisms and models may underlie all forms of adaptation to intersensory and sensory-motor misalignment.
